RDFa is a W3C standard for embedding semantic metadata directly into HTML web pages. While early work on RDFa dates back to 2004, it recently gathered a lot of uptake and traction through the adoption by big players such as Google, Yahoo! and Facebook. This has put the Semantic Web into the attention of a much wider public, setting RDFa out the be the technology to finally bring the Semantic Web into the mainstream. The language gained the status of a W3C recommendation in late 2009 as RDFa 1.0. Since then, the RDFa working group has been established to improve and extend the standard. Eventually, this work will result in a new version of the language, which is set to be released as RDFa 1.1 in 2011. In this talk, an overview will be given of the RDFa technology in general, followed by an outline of its latest developments, such as the RDFa API, or the definition of RDFa Core, which prepares the standard to extend its scope beyond the context of web pages, by allowing it to be included into any other markup language than just HTML.

Libraries contain masses of beautifully structured data collected over many years. But these records may have their flaws and might now want to be used in ways, such as location based services, that weren’t imagined 30 years ago. How can we use existing API’s and web services to enrich this data to enable it to be used in a variety of ways. This data also needs to be exposed for others to use and build upon. With the recent release of the Government response to the Web 2.0 taskforce, how can institutions comply with these recommendations by providing their data in usable forms for the public. What’s involved in building an API into our resources and how can our data be given more meaning through semantic linkages like RDFa?
